Don’t remember where I saw this…
A very rich man dies and arrives at the pearly gates with a large heavy bag on his back. St Peter asks him, “What’s in the sack?”
The man replies “I’ve given most of my riches to the poor, and I thought I could just bring a small amount with me to heaven”.
Peter says, “Mmm. I’ll have to ask God if you’re allowed to bring this in.”
After a while, St Peter comes back and says it’s probably fine, but he has to check the bag. He opens it and discovers it’s full of gold bars.
“Oh!”, he says, “That’s OK. You’ve brought paving stones.”
